Novel Photocrosslinking Resin by Photooxidation Induced Polycondensation

Polycondensation of furan derivative by singlet oxygen, which is generated using the sensitizer such as fullerene C60, is applied to the crosslinking of polymers. A polymer having furan units in the side chains was synthesized by the polymerization of furfrylmethacrylate with 2, 2'-azobis (isob...

Summary:Polycondensation of furan derivative by singlet oxygen, which is generated using the sensitizer such as fullerene C60, is applied to the crosslinking of polymers. A polymer having furan units in the side chains was synthesized by the polymerization of furfrylmethacrylate with 2, 2'-azobis (isobutyronitrile). A 1, 1, 2, 2-tetrachloroethane solution of the polymer was exposed to visible light in the presence of several sensitizers. The solution turned to a gel after several hours and then solidified completely. Photochemical studies and quantum calculations reveal the predominant of fullerene in photocrosslink-ing of the polymer.
